You're correct you don't need 10" wheels to run a 275, but you might as well buy 255s then. You'll end up with the amount of tire to the ground. With 9s and 275s I found the tread would become rounded and not touch the ground.

If you are just driving on the street and only looking for looks, 9s all the way around should be fine. You will get a little more oversteer at speed, and your turn in will be much improved. You will also tramline like a big dog.

Yeah, I'm not too big on the idea of using the same size tires all around- I thikn POrsche did a good job designing this car for the most part & I know they have the front & rear track made to work w/dif sized wheels, etc, so I hate to mess w/that- of course, the real benefit would be being able to rotate tires- I don't think it would be worth it though...

as for the 255 & 275 having th e same amount of tire on the road & the funny wear pattern- I know what you're saying, but, I don't see why this doesn't happen on the fronts at all then(?). No big deal either way- I'm really not planning on 275's anyway- I MAY do the 265/40/17 w/either 225/45 or 235/45/17's (depending on whether or not I locate 7" or 7.5's w/the 993 wheel's), but, it all depends on many variables- I wont go w/275/40/17's though- I KNOW that- too tall profile IMO- it would be almost idetical to what I have now (110 vs 110.25 w/my 245/45)- part of the benefit of the 255/40/17 (or 265/40/17) is the lower profile (but not TOO low)- IMO less than ~100mm is too low for these streets). IF 18's, then I MIGHT do 275's, BUT, w/35 instead of 30's... STILL might be a tight fit & I doubt it will happen anyway- REAL hollow spokes don't usually show up for the relative price of 993's...

The cup 2s are much cheaper than a nice set of hollow spokes, and IMHO I think they look better on our cars.

I'm pretty sure that all of the cup 2s are 7/9x17 and not 7.5 though. You can get cup 1s in 7/8/9/9.5, but pay the weight penalty we already discussed.

Your 225/45 and 255/40 would be a nice handling and lookig combo...

I always liked the C2's better thasn anything except for Club Sports (I liked them both the same except that CS's didn't come in 17's) until the hollow spokes came out- I don't like the other type of twists as much- the hollow spokes are different- the 993's are next down on my list, but, they are the lightest- even a HAIR lighter than the CS's & since they're 17's, it's really the only way I think I'll go- I HATE that the C2's aren't the swame weight- they add ~4lbs per wheel- I just can't do it- I'm a freak, I know...

AS for sizes, the C2's AND 993's BOTH came in 7.5's as well as other sizes you mentioned- not sure about replicas though- I've talked to Wheel Enhancement about it & everything- not that they are the end all be all, but... I'm SURE the 968 had the 17x7.5's up front w/BOTH versions. They did a really good thing there- it didn't really help any, as the 968 M030 didn't do nearly as well as the Turbo S, but, part of that was power- it just didn't seem to help corner any better either, for some reason- COULD be that some of the cars are just not as strong from the factory as others- I KNOW there are variables all the time w/ALL cars, but,. the 968CS ran WS in 143.3 whereas the Turbo S ran it in 1:41 even, years before...

Trivial, but creepy, I just realized that Robby, C5Driver951, and myself all registered in Jun of 2001... God, I wish work would go faster. I'll Try to post pics of my C2's and rubber after work in the AM.

Robby

Actually, I think that was when the server went down & John re-connected everything differently & we all had to re-register- I have been messing w/this board since Summer 2000 & registered almost immediately- when I first got my own computer- I had played around w/the board just a few times when I first bought my car (10/99) on other people's computers... Anyway, I think a lot of people re-registered in June 2001 b/c of the crash & the fact that they were already established here....

C5Driver951

True dat. I've been around in some form or another since 1997 from PorscheFans to PorscheList to Rennlist and the boards. I just don't spend as much time looking at this stuff as I'd like to...

Robby, Thanks for the info. I will never do relpliwheels for the track again. The last set I had started to crack near the hubs. Too bad you can't deal with the C2s being a bit heavier. There's a set of 17x8/9.5s in the classifieds. I had a set of these at one time and they are sweet. I'd buy them, but I have two sets of CSs for track wheels. I don't like the twists that much, but am thinking of buying a set of hollow spokes for track wheels for the weight and handling. I'll either go that route or CCWs.

Robby

Man, I KNOW- I LOVE the way the C2's look- I'm so torn on the decision, as I like the looks of the C2's better, but the weight of the 993's... The 8's & 9.5's you mentioned- are you SURE they're REAL factory's? I didn't know they had 9.5's in factory's(?)- I thought it was just 7, 7.5, 8, & 9(?)...

BTW- you may already know this, but, the hollow spoke looking twist is different than the Boxster looking twist- they are really dif looking wheels when up close- I never liked the other's too much, but the thicker, more ridged looking spoke of the hollow spoke along w/the way the spokes come together, makes the wheel look much better IMO... Also too bad the Club Sports don't come in 17's- I would love to have either C2's OR CS's (or HS's) on the car. Which CCW's are you talking about? Do you know how much they weigh? I really like the factory wheels on these cars better than anything I've seen, although there are a few aftermarkets I like- it's just that most of them are SO expensive- if paying that much, I'd go w/Hollow's-of course, I know you dont care for them as much, but... BTW- they aren't as light as many think- they're light for their size, etc, but, I think the narrowest on weighs a hair over 20lbs- is that a 7x18? 7.5x18 maybe? not sure...

The hollows I am talking about are from the 993 twin turbo. I know of a set of early ones with a larger offset than typical. As far as I know the real hollow spokes were all 18x8.5/10. The later 996 twists, Boxster, and the C4S versions were not hollow... Personally, I'm not a big fan of the looks of them on 944s. Magown and another one of my friends both have the Boxster/996 style and like them. Stephen had some rubbing issues until he put a little negative camber in.

Yes, the C2 wheels do come in a 9.5" width. They were produced for the Carrera Cup cars. The typical set up you will see is 17x8/9.5. I can look the part numbers up if you like, but the 8s are the rears off of a RS America and the 9.5s were special order (read rare). I had a set I bought from G&W racing. I sold them prior to getting rid of my 911, a decision I've always regretted.

John at CCW Wheels does a lot of race wheels for a number of different series. If you search CCW Wheels on the list and net you'll find lots of info. The beauty is you can get 4 brand new wheels for ~$1800. They aren't the prettiest, but the are light and strong.

I run 275/30/18s. You should be fine.

Robby

That's cool- I wasn't aware of that- as for 275/30/18- that wouldn't be as large as 275/35/18 though- that stands the wheel up that much more- I'd be afraid to try unless I knew someone else had done the exact same thing- those 18's are expensive- both tires & wheels....
